Distribution. — San Francisco Island, Gulf of California, 

 Mexico. 



Variation. — Only one of the 1 7 specimens has the scales 

 of the collar largest at its edge. One has the supraoculars 

 4-4, one 4-3, and the others 3-3. 



Remarks. — This lizard is most closely related to V. 

 sericea of San Jose Island. It differs from that species in 

 the almost complete absence of red on the sides of the body 

 and in the frequent posterior forking of the dorsal line. 

 V. ccertilea of Carmen Island also is closely related, but 

 has still more red on the sides and back of the body. These 

 three species differ from all the others in being blue below, 

 without any orange.
